摘　　要：通过悬挂式自然供氧工艺,分别采用聚对苯二甲酸乙二醇酯、聚酰胺6和聚丙烯腈3种纤维材质的绳式生物膜载体对COD为(400±5)mg/L的果糖废水进行处理,比较了3种生物膜载体的挂膜效率。结果表明,聚对苯二甲酸乙二醇酯纤维材质生物膜载体挂膜效率﹥聚酰胺6纤维材质生物膜载体挂膜效率﹥聚丙烯腈纤维材质生物膜载体挂膜效率。在温度为20～25℃条件下,运行10.42 h后,聚对苯二甲酸乙二醇酯纤维材质生物膜载体下端5 m处出现1.0 mm厚度的生物膜。Three kinds of rope-like fiber biofilm carriers （polyethylene terephthalate, polyamide 6, polyacrylonitrile ） have been used respectively for treating fructose wastewater whose COD is （400~5） mg/L by means of lift-type carri- er and natural oxygen supply. Their film formation efficiencies are compared. The results show that their biofilm growth efficiencies are ：polyethylene terephthalate 〉polyamide 6 〉polyacrylonitrile. After running for 10.42 h, the biofilm with a thickness of 1.0 mm is emerged at the lower extreme about 5 m of the biofilm carrier which has been made bv oolvethvlene terenhthalate at 20-25 ℃.
